3801754 Turbocharger Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured low pressure turbocharger, weighing 29.484 kg and listed for four TWD applications. The reman catalogue records it as the low pressure stage on the TWD1672GE and TWD1673GE, working with high pressure unit 3801142. It supersedes 3801141, which the catalogue lists as the low pressure stage on the earlier TWD1643GE to TWD1645GE and TWD1663GE - the same duty under an earlier number. The low pressure and high pressure units are not interchangeable. Supplied on an exchange basis: core deposit 3804754 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
